The Zone of Inhibition (ZOI) is an area of no bacterial or fungal growth that surrounds an antimicrobial agent, such as an antibiotic, antifungal, or disinfectant, that has been applied to a culture of microorganisms on a petri dish. The Zone of Inhibition is used to measure the effectiveness of the antimicrobial agent in inhibiting or killing the growth of the microorganisms.
The size of the Zone of Inhibition is determined by measuring the diameter of the clear area around the antimicrobial agent where no growth of microorganisms is observed. The larger the Zone of Inhibition, the more effective the antimicrobial agent is in inhibiting or killing the microorganisms.
The Zone of Inhibition test is commonly used in microbiology to evaluate the susceptibility of microorganisms to different antimicrobial agents. This test is often performed to determine the appropriate treatment for bacterial or fungal infections and to monitor the effectiveness of antimicrobial agents over time.
Overall, the Zone of Inhibition test is a valuable tool in the field of microbiology for assessing the effectiveness of antimicrobial agents against specific microorganisms and for helping to guide the selection of appropriate treatments for infectious diseases. learn more about School Management System.
